100% Merino Wool Shirts for Men - Thermal Underwear Base Layer Long Sleeve

I picked up this merino wool undershirt to survive the arctic conditions otherwise known as my office, and it has already earned MVP status. It’s lightweight, soft, and somehow manages to keep me warm without feeling bulky. The fit is comfortable enough to wear all day, which is good, because the thermostat at work seems permanently stuck on “January in Siberia.” Since switching to this shirt, I’ve spent far less time wondering whether I should bring a blanket to meetings. It holds heat well, breathes nicely, and doesn’t itch—basically everything you want when you’re trying to look professional while quietly shivering. If your workplace also believes in aggressive air‑conditioning, this merino layer is a solid investment. At the very least, you’ll look less like you’re preparing for hypothermia during conference calls. The price is pretty good and it fit me just right.

It is seldom that a product exceeds expectations but this shirt is a perfect base layer. Expensive as an undershirt but great value for money. If you are wanting to turn the thermostat down but don't want to bulk up like blimp in your living room here's your solution. Merino is a wonder material. It attracts almost no sweat or smell. hang it outside in freezing weather and it will self clean. Amazing stuff.

I have a couple of these wool Henleys and I love them. This is made from 100% merino wool, soft and warm, and the jersey weave has plenty of stretch and give so the fit is always perfect, even after several washings. The style is classic, and since it's a mid-weight shirt, it's comfortable for at least ten months out of the year. I've had this shirt for almost a year and it's holding up beautifully. As for the price, I paid a little more for this shirt because I wanted this particular color (olive green), but it's still much less than I would have paid for the same shirt from other merchants, so I can't complain. Definitely a good buy.

I've bought many merino base layers. This recent acquisition is well assembled and the material was soft after initial wash. It's not super thick, but for the price, it is good value. I am a medium build 5'11" man and medium size was a good fit, just snug enough but breathy. Took of one star because the color in the picture is way off. It's not as bright blue. More like a darker denim blue/grey. The purchase decision was partly on the color, so this inaccuracy was disappointing. Still a good garment, imo.

This fabric is my favorite base layer: warm, comfortable, and allows moisture to pass to the next layer. I have several versions for travel and tletics. Not sure how many wash cycles it will survive, so I launder it gently and it air dries overnight unless the ambient air really humid.

This is actually my second one of these I purchased, the first one was black so I got a different color to keep up with them. I don't know about temperatures in the teens or minus figures but I can say I'm totally comfortable wearing this under a long sleeve shirt. I have never gotten hot or cold, from being in the bitter cold - warm and coming inside to 75 degree temperature - hot. Great product. I also have their socks and a hoodie also and all are great products. Customer Service is prompt, helpful and great also. 5Star all the way.

A plus for being a 100% merino wool. But the fit wasn't right for me... it didn't feel properly structured in where the arms are connected to the body (hard to describe). I'm 5'11" 168 lbs.

Great shirts, feels good against my skin and warm. Wears well underneath another shirt, doesn't bind up.

Fits great, feels good & lots of compliments!

Satisfait de mon achat, la taille recommandée était la bonne, matière confortable, légère.

Ein wunderbares Material - leicht und doch etwas wärmend - atmungsaktiv und angenehm zu tragen ! Ich mag kein normales Funktionsshirt- das Material aus Kunststoff finde ich sehr unangenehm . Dieses Shirt ist perfekt - der Sitz und die Länge sind für große Frauen auch super !

This shirt is amazing. Soft and comfortable. Perfect as an all season, versatile, undershirt or wear it alone. Very stylish. Lots of colour options to choose from. This one is not meant for frigid temperatures, for that you would need the 320g

Tengo ropa merino de varias marcas. Si bien Merino Tech no está a la altura de las "reconocidas": Wool & Prince o Unbound, aún así ofrecen una experiencia placentera. Son suaves y livianas y abrigan lo que uno espera en clima frio o dejan respirar en clima caliente. Tengo esta en azul y otra en negro, las cuales uso en situaciones informales. Lo único objetable es el logo de la marca en el puño, ello no es elegante... y a mí personalmente me molesta comprar/pagar algo para luego involuntariamente andar haciendo publicidad de la marca.
